In this study, a method based on ejector technology is proposed to effectively suppress the infrared radiation associated with exhaust gas of special vehicles such as tanks, armored vehicles, and missile carriers. These emit gases at very high temperatures. First, mathematical model pipe was established for system certain type vehicle. Then, 3-D flow field outside numerically simulated using FL...

Lubricating oil is known as "the blood to maintain the normal operation of machinery", and additives are an indispensable important part lubricating oil. In this paper, Polymer-based Composite Nano-additive (PCNA) suitable for armored vehicle engine was developed, physical chemical properties containing were carried out. The results showed that adding appropriate amount (3 vol.%) could improve ...

The analysis of materials on approaches, methods and models research strength durability torsion shafts systems suspension light armored vehicle is carried out. It concluded that despite the existing significant theoretical developments, elastic-plastic deformation highly loaded structures, including shafts, requires development adaptation appropriate models. approach to a number studies this i...

We verified the analytical performance characteristics of a previously described real-time reverse transcription-PCR (RT-PCR) assay targeting the open reading frame (ORF) 1b region of the severe acute respiratory syndrome coronavirus (SARS-CoV) with RNA transcripts. We then compared it to a novel nucleocapsid gene real-time RT-PCR assay with genomic RNA. The assays differed only in the primer a...

Cash movements between banks and customers are often conducted through armored courier services. These couriers hesitant to adopt new technologies because the business’s nature requires well-documented custody transfers of cash bags. Often, these still based on paper receipts. The researchers believe that using radio frequency identification (RFID) an application programming interface (API) all...

Resource subsidies increase the productivity of recipient food webs and can affect ecosystem dynamics. Subsidies of prey often support elevated predator biomass which may intensify top-down control and reduce the flow of reciprocal subsidies into adjacent ecosystems. However, top-down control in subsidized food webs may be limited if primary consumers posses morphological or behavioral traits t...
